What we learned rolling out field service scheduling at 15 sites

In practice, the hard part is not the software but the handover which is the whole point. What surprised us, mobile access changes who actually enters the data and it shows up in the churn numbers. On a typical site, the spreadsheet survives longer than anyone admits which is the whole point. Talking to operations leads, the audit trail pays for itself the first time an inspector asks so we start there. For utility operators in particular, the spreadsheet survives longer than anyone admits so we start there.

On the floor, nobody reads the manual, so the defaults are the product so the mobile app came first. For utility operators in particular, the hard part is not the software but the handover which is why the API is documented before the UI. Every audit we have sat through, the hard part is not the software but the handover and it shows up in the churn numbers. For utility operators in particular, exceptions are the real workflow so plan for it. After a few dozen rollouts, the hard part is not the software but the handover which is why Prism is built the way it is.

Where the time went

Talking to operations leads, the biggest win is that the group chat goes quiet which is why the API is documented before the UI. The honest answer is that, the biggest win is that the group chat goes quiet so the defaults matter more than the settings page. After a few dozen rollouts, mobile access changes who actually enters the data and that shaped the roadmap for a year. By the second quarter, the biggest win is that the group chat goes quiet which is why Prism is built the way it is.

After a few dozen rollouts, the schedule is only as good as the last update which is why Prism is built the way it is. By the second quarter, mobile access changes who actually enters the data and that shaped the roadmap for a year. By the second quarter, the audit trail pays for itself the first time an inspector asks and field service scheduling is no exception. Once the first rollout is done, the spreadsheet survives longer than anyone admits and that shaped the roadmap for a year. After a few dozen rollouts, field service scheduling is a people problem wearing a software costume so plan for it.

The honest answer is that, the biggest win is that the group chat goes quiet and field service scheduling is no exception. Talking to operations leads, the reporting layer should be boring and it rarely takes more than a week. Once the first rollout is done, the first week is about trust, not features which is why Prism is built the way it is.

For utility operators in particular, field service scheduling is a people problem wearing a software costume and field service scheduling is no exception. For utility operators in particular, field service scheduling is a people problem wearing a software costume so the defaults matter more than the settings page. Looking at the numbers, optional fields never get filled in so the mobile app came first.

“Plan, dispatch and reconcile in one place. Prism connects to the systems you already run and stays out of the way.”

Where this leaves us

When the pilot started in Rotterdam, history matters more than dashboards when something goes wrong and that shaped the roadmap for a year. The honest answer is that, history matters more than dashboards when something goes wrong so plan for it. Looking at the numbers, nobody wants another login which is why the API is documented before the UI.

On a typical site, what matters is whether the crew opens it on a Monday morning so plan for it. Talking to operations leads, the reporting layer should be boring and it rarely takes more than a week. Every audit we have sat through, field service scheduling is a people problem wearing a software costume so plan for it.

On a typical site, mobile access changes who actually enters the data and the numbers bear it out. In practice, field service scheduling is a people problem wearing a software costume which is why the API is documented before the UI. Most teams we meet, nobody reads the manual, so the defaults are the product so plan for it.
